Migration Director Jose Ricardo Taveras said that business owners will have one month to comply.  He said he rejected pleas by several business groups to further postpone enforcement of the regulation out of growing concern that it would result in a loss of productivity and revenue. The Agrobusiness Board said an estimated 80 percent of workers in rice fields and 60 percent of those in banana fields are Haitian migrants.
